Daval International Limited Release: Open Label Clinical Study Results of AIMSPRO® in the Treatment of Progressive MS Suggest the Drug Stops Disease Progression and May Have Some Restorative Effects

Eastbourne, UK – Daval International Limited recently presented a poster at The 2013 Annual Meeting of the Consortium of Multiple Sclerosis Centers (CMSC) and the Fifth Cooperative Meeting with Americas Committee for Treatment and Research in Multiple Sclerosis (ACTRIMS) in Orlando. The poster, entitled “Clinical benefits reported with AIMSPRO® treatment in progressive multiple sclerosis: open-label observations”, was presented by Dr Christopher Moore from Queen Alexandra Hospital, Department of Clinical Neurophysiology, and the University of Portsmouth, UK. The encouraging results contained in this poster further underscore AIMSPRO’s broad potential as a novel therapeutic agent to treat a number of autoimmune, inflammatory and neurodegenerative diseases.

Dr. Moore presented data from a centralised retrospective analysis of clinical outcomes from 154 patients with confirmed progressive multiple sclerosis (the majority having the secondary progressive form of the disease) with a mean disease duration of 13.6 years and no preceding relapse within 1yr recorded. Patients were treated with subcutaneous injections (1ml per dose) of hyperimmune caprine sera (AIMSPRO®) over a prolonged period of time (maximum 3 years). The analysis is based on self and physician-reported clinical efficacy measures in the 140 patients with documented follow-up/assessments. All clinical improvements, observed or reported were scored in alignment with the expanded disability status score (EDSS) ‘equivalent’, an estimate of the change in the numerical scale that might be expected had formal clinical grading been undertaken prospectively. A +2 improvement would likely reduce a patient’s symptom score by an EDSS of 0.5. More than one +1 improvement would be needed for a similar overall change. Changes in the 8 areas of sensory/pain, motor, bladder, ataxia, sleep, vision, energy, and ‘other’ were scored.

The results of the analysis revealed that the treatment was both safe and well tolerated. In the study, 100 patients had clear improvement in > 2 functional areas (motor and sensory/pain) and as such were likely to have a change of at least -0.5 in their EDSS score. 122 patients showed clinical benefit in > 1 areas. 16 patients reported no overall benefit, 2 patients showed overall worsening by 1 point in 1 area. These clinical observations suggest that AIMSPRO® therapy stopped the decline in progressive MS and may have a restorative effect in multiple clinical areas.

Professor Syed Haq, Chief Medical & Scientific Officer at Daval International and co-author of the poster, commented at the meeting, "The findings of this open-label study are very encouraging for the future development of a medication that could address secondary progressive multiple sclerosis, which at present has no approved treatment. For an efficacy signal to emerge with a therapeutic for SPMS implies that the drug must be concomitantly modulating a number of biochemical pathways. These include perturbation of inflammation, repair of damaged neurons and neurogenesis. Thus the results from this study further underscore AIMSPRO’s broad potential as a novel therapeutic agent to treat a number of autoimmune, inflammatory and neurodegenerative diseases”

The CMSC annual meeting brings together healthcare professionals and researchers involved in MS clinical care or research who are committed to improving the lives of people with MS. The goal of the Annual Meeting is to provide the most up-to-date information impacting all facets of MS patient care.
